Pdf can support page sizes up to miles long or wide.... (although this is slightly absurd, but yes, MILES long!) but if you create a large page in InDesign you are met with a lovely error message when you come to export. Larger page sizes would be beneficial for lots of reasons, app prototyping, print, really long articles and pictures of Giraffes ;-)

Seriously though, please oh wise Adobe can you increase this limitation to a more reasonable number, Thank-you.
